Description
【発明の詳細な説明】 車両設備駆動用モータ減速装置 本発明の主題はモータ減速装置、特に回転子軸、シール手段と共にダンパを含 む歯車と噛み合うエンドレススクリュを含む減速ギアボックス、およびダンパに より回転する出力部材を具備した回転子から成るタイプの車両設備を駆動するた めのモータ減速装置に関する。 現在のモータ減速装置の減速ギアボックスは次の部品で構成される。即ち、歯 車、ハブ、リップシール、カバー、窓昇降機ケーブル等のケーブルを巻取るプラ スチックドラム、または焼成鋼で形成されたピニオン、およびオーバーモールド されたプラスチックハブから成る。 この構成は比較的多数の部品を含み、このことは製造コスト高に繋がる。 更に、モータ減速装置に取付けた軸の線に軸方向の遊びが生じる。この軸方向 の遊びは、その収容ハウジング内に端から端まで設置された組立体の各種部品( 軸、ストッパ、ボックス、ケース等)の体積の全体的広がりによるものである。 従来、この軸方向の遊びは回転子軸の孔に対面するボックスの端に収容された 螺子を手動操作することにより補正され、かつ同時にシールを形成する接着剤に より固定されている。このような調整法が長時間を要し、そのためにモータ減速 装置の製造コストを高価にする。 米国特許第5,169,245号は軸方向の遊びを、回転子軸の端部に軸方向 スラストを与えるコイルばねを使用し、このばねの一 部を挿入し、所定量の圧縮力を加えたときにボックスのショルダにばねの一部を 当接させることにより補正する。かかる装置において、ばねは軸力の作用により 圧縮し、かつモータ減速装置の回転方向が転換するときにばね内に蓄積されたエ ネルギは突然解放される。そのようにして、回転子軸の反対端部が固定子の端部 を激しく付勢し、これが非常に煩いノイズの原因になる。 最後に、他の問題は、リングがモータ減速装置の軸と固定子間で縮むことであ る。これは固定子の端部におけるハウジングの直径が不規則である結果としてリ ングの内径が変化することによる。従って、軸とリング間の半径方向の間隙が不 規則となり、これが軸の煩い振動原因となる。 本発明の課題は、既知モータ減速装置と比較してその構造が簡略化され、従っ て、低製造コストのモータ減速装置を製造することにある。 本発明は、また、軸の振動を減少するために、回転子軸と固定子間に挿入され るリングと回転子軸間の内径の制御をより良くすることを課題とする。 本発明の他の課題は、簡単、効果的かつ安価で、調整装置の損傷の危険を伴う わない手段を使用することによりモータ減速装置の軸線の軸方向の遊びを自動的 に補正することにある。 本発明によれば、シール手段は歯車の環状壁、および前記環状壁とボックスの 壁間に配置されたシールから成り、このシールは前記ボックスに固定されかつ前 記環状壁上に慴動により当接するか、または前記環状壁に固定されかつ前記ボッ クス上に慴動により当接して前記シールの少なくとも1つのリップと前記環状壁 間にシールを形成する。 本発明の1つの特徴によれば、ダンパは1片として形成され、一 方で歯車の半径方向のフィンを収容し、かつ他方で出力部材を駆動するための要 素を収容するように設計さた複数の周辺切欠きを有し、かつこの切欠きの縁部は 面取りされている。 本発明の1形態によれば、前記ダンパはその少なくとも一面上に前記歯車と前 記出力部材とにより画定されかつ圧縮時に前記ダンパの膨張に必要な容積を提供 するキャビティ内にセンタリングする手段を具備する。 前記ダンパの面取りは2重の利点を有する。即ち、一方でトルクの関数として ダンパの角偏向を漸次的にし、他方で、ダンパの前記歯車のハブ上への自動的固 定をより容易にする。 本発明の他の特徴によれば、モータ減速装置は前記ダンパ、前記シール、およ び前記歯車と同軸のドラムで構成される出力部材から成り、このダンパは歯車内 に収容され、そこに固定されてそれらが一体として回転するようになっている。 前記ドラムは特にケーブル操作式の窓昇降機用のケーブルを受けることを目的と している。このドラムは前記ダンパに固定するための手段を有し、この両者が一 体として回転するようになっている。 前記固定手段は前記ダンパと共働する前記ドラムのフィンガ部で構成されてよ い。 このように、前記ダンパそれ自体は前記ドラムを、中間プラスチックハブに代 って、直接的に駆動する。従って、中間プラスチックハブは省略できるので系の 部品数を減少させる。 本発明の他の特徴によれば、前記出力部材は前記歯車内のハブを有する単一片 として形成されたピニオンであり、好適には焼成鋼で形成される。このピニオン とハブの単一片形態は焼成ピニオン上にハブをオーバーモールドすることにより 形成される対応する従来部品のコストとの比較で製造コストを節減する。 本発明の他の特定形態によれば、軸方向の遊びを自動調整する手段は弾性材に より形成された減衰ストッパ、およびこのストッパ内に埋設された金属ワッシャ から成り、軸方向の遊びを自動的に補正するためにその軸の端部は予備荷重によ り前記ワッシャを付勢する。 このストッパ装置はモータ減速装置が作動するときに前記ダンパにより加わる 軸方向の圧縮荷重を所定値に制限することができる。 更に、コイルばねではなく弾性ダンパを使用することによりコイルばねに関す る欠点を解消する。実際に、弾性要素は弾性材料の分子鎖間の内部摩擦による変 形のエネルギのいくらかを吸収する性質を有する。この軸受け力により生するエ ネルギのいくらかの吸収はモータの方向転換時の煩いノイズ音を相当に減衰する ことができる。 前記ダンパによる最大力は標準的力によれば、例えば、100ニュートンであ る。この値を越えて、モータ減速装置の運転時に回転子軸により伝達される軸力 がストッパ装置を介してボックスの壁上に加わり、かつこれは前記ダンパが過剰 軸力により損傷を受ける危険性を解消する。 前記剛性ストッパは前記回転子軸の軸を中心に回転することを防止する手段を 具備するのが有利である。 本発明の他の特徴および利点は非制限例として添付図面を参照する次の説明か ら明らかにされるであろう。 図1は本発明によるモータ減速装置、特に減速ギアボックスの1形態の部分分 解図である。 図1Aはギアボックスの壁と歯車のカラー間のシールの図1の22の部分断面 図である。 図2は回転子軸の1端部とギアボックスの壁の長手立面部分断面 拡大図であり、本発明による軸方向の遊びを自動的に調整するための手段を示す 。 図3は回転子軸の1端部と固定子の長手立面部分断面拡大図であり、回転子軸 と固定子間に挿入された本発明によるリングの1形態を示す。 図4はモータ減速装置の出力部材を構成してよいピニオンの斜視図である。 図5は本発明による軸線における軸方向の遊びを自動補正する装置を具備した モータ減速装置の長手立面部分断面図である。 図6は回転子軸の端部とギアボックスの壁間の軸方向の遊びを調整する手段の 1形態の図1よりも拡大した部分断面図であって、その装置は負荷を加える前の 静止位置にある。 図7は図6の7/7線の断面図である。 図8は軸線上に組立られたモータ減速装置の無負荷位置の軸方向の遊びを自動 調整する装置を示す図6と同様の図である。 図9はモータ減速装置の作動時の位置における装置を示す図8と同様の図であ る。 図10は自動遊び補正装置のダンパにより加わる圧縮力の関数としてモータ減 速装置の軸線上へギアボックスにより伝達される軸力の変化を示すグラフである 。 図1から4に示されたモータ減速装置は特に電動窓昇降機等の車両駆動設備用 を意図している。 このモータ減速装置は1端部1が図示された(図2)回転子軸を具備した回転 子(図示せず)、前記回転子軸に垂直にその軸4上に取付けられた歯車3を含む 減速ギアボックス2から成る。ギアボックスは歯車3と噛み合うエンドレススク リュ(図示せず)から成る。モータ減速装置は更に歯車3内に収容されかつその ハブ6と同心 に取付けられる単一片ダンパ5を含み、これは好適にはエラストマー等の弾性材 により形成されるダンパ5の半径方向の対応する切欠き8に係合する半径方向の フィン7を更に含む。切欠き8の縁部は面取り面90に形成されている。 ダンパ5は歯車3と出力部材11との間に画定されるキャビティ内にセンタリ ングする手段を少なくともその1面上に具備する。この例において、これらの手 段はダンパ5のレスト(rest)と一体成形されてその面から突出するスタッ ド98で構成される。スタッド98は上述のセンタリング作用を付与しかつ圧縮 されるときにダンパ5の膨張に必要な容積を提供する。 最後に、減速ギアボックス2はダンパ5ならびに歯車3と同軸の環状シール9 およびドラム11を含む。このドラムは特にケーブル操作式窓昇降機のケーブル を受けることが意図されかつモータ減速装置の出力部材を構成する。シール9は 減速ギアボックス3へ圧力嵌めされる金属ワッシャ40(図1A)上に、例えば オーバーモールド(overmoulding)により製造される。シール9は歯車3の内部 環状壁12に慴動して当接する少なくとも1つのリップ9aを有する。環状壁1 2は、歯車3−ハブ6間の結合がこのハブの外側であって軸4と歯車3間に挿入 されないので必要である。 他の形態として、前記シールはカラーに固定でき、かつそのリップはギアボッ クス2の壁上を慴動する構成であってよい。 内部環状壁12は歯車3の歯に対して長手方向でドラム11に向かって僅かに 突出する。環状壁12とボックス2の壁13間に設置される環状シール9は、こ のようにして、カバー設置の必要なく、ギアボックスをシールする。 この目的から、例えばギアボックスに弾性係止するタブ14により、シール9 はギアボックス2の壁13に固定し、かつ慴動させて 環状壁12の周辺に付勢するか、または例えば環状壁12と歯車3の基部間の空 間へ堅く取付ける等の適宜手段により環状壁へ固定し、かつ慴動させて壁13に 付勢する。 ドラム11はダンパ5に固定する手段を具備し、それによりダンパと一体的に 回転する。この図示形態において、この固定手段はドラム11のフィンガ部10 で構成され、フィンガ部10が半径方向の対応する切欠き8と係合する。例えば 6個の切欠き8が形成され、その内の3個がフィンガ10を受け、かつ他の3個 がフィン7を受ける。この構成によって、従来使用されていたモータ減速装置の 中間プラスチックハブを省略でき、ダンパ5はドラム11を直接的に駆動する。 本発明の他の形態において、モータ減速装置は歯車3の環状壁12の内側にハ ブ17(図4)を有する単一片として形成されたピニオン16で構成される出力 部材15を含む。出力部材15は好適には焼成鋼で形成される。ハブ17は対応 する切欠き8と係合するフィンガ30を具備して出力部材15のダンパ5への固 定を可能にし、それにより両者が一体的に回転する。 モータ減速装置は回転子軸の端部1とギアボックス2の壁18(図2)間の軸 方向の遊びを自動調整する手段を具備する。この図示例において、この調整手段 はゴム等の弾性材で形成され、壁18によりこの点で画定される容積を充填する 減衰ストッパ19、およびそのストッパ19に埋設された金属ワッシャ21から 成る。更に精確には、ワッシャ21は軸1に対面するストッパ19面内に収容さ れ、それによりワッシャ21の表面はストッパ19を横切る面と融合する。 軸1の端部はワッシャ21を付勢するプラスチックキャップに固定されている 。回転子軸1、端キャップ22、ワッシャ21、およ びダンパ19により構成される組立体は軸1の軸方向の遊びを自動補正するため に壁18内に僅かに予備負荷を与えて取付けられる。 モータ減速装置の他の特徴によれば、ストッパ19の反対端部である回転子軸 の端部23は半径方向の2段部25,26により形成されたリングベアリング2 4内に取付けられる。 第1段部25は付勢する固定子20の内壁の直径に等しい外径を有し、他方、 その内径d1は軸23の外径dよりも大きい。第2段部26は付勢する軸23の 外径dと同一内径を有し、かつ外径d2は固定子20の内壁の直径よりも小さい 。 このように、回転子軸の端部23と第1段部25間に環状ギャップ27、およ び第2段部26と固定子20間に環状ギャップ28が形成される。 軸23と接触する第2段部26上でその直径が、固定子20の内壁からギャッ プ28をおいた寸法であることから、変化することがないので、この段付きリン グ24は軸23の遊びの制御を改良する。従って、この壁の不規則性は第1段部 25のみへ伝達され、第2段部26による負荷が第1段部25へ伝達される。従 って、軸23の振動は評価できるほど減少する。 図5のモータ減速装置100は特に電動窓昇降機等の車両駆動用を目的として いる。 ケーシング200内に収容され、既知方法において電気的接続400により印 加できる固定子300、端部が軸受け700,800に取付けられた回転子軸6 00を具備した回転子500から成る。この回転子軸は、例えば窓昇降機、サン ルーフ等のモータ減速装置に接続された装置を駆動する出力部材120を駆動す る歯車110と噛み合うエンドレススクリュ900を担持する。 モータ減速装置の作動時に回転子軸600により加わる軸力Fの 均衡を保つために、エンドレススクリュ900の近傍で軸受け700を通る回転 子軸600の端部600aは端部600aと減速ギアボックス140の壁130 間の軸方向の遊びを自動補正するための装置120と共働する。 図示形態において、上記調整装置は、ボックス140の壁130の端部の端ハ
